A Generalized Three Invariants Cap Model and its Numerical Implementation to Study Soil-Foundation Interaction
This paper presents a modified cap model that is capable of characterizing cyclic stress-strain behavior of soils and describing variation of shear strength along various stress paths...

Deriving Alternative Structural Modifications Based on Qualitative Interpretation at the Conceptual Design Stage
Current computer tools provide little support in deriving alternative modifications based on qualitative structural interpretation of a conceptual design. This paper presents a behavior-based...

Reliability Assessment of Concrete Pavement Sawing
Traditional concrete pavement design sometimes realize on qualitative decision based on experience, with concrete pavement sawing operations representing a specific case in point. presently,...

New Wells Safeguard Scenic Tahoe
Surface water for drinking and for snow-making is becoming scarce in the Lake Tahoe region, along the California and Nevada border. New Environmental Protection regulations regarding surface...

Estuary Management: The British Experience
This paper describes two estuary management studies undertaken in south-west England during 1991-92. Despite there being many differences between the studies in terms of why they were...

Results from Minerals Management Service Funded Oil Spill Response Research 1991-1993
Large oil spills from tankers have reaffirmed the need for continuing technology assessment and research to improve oil spill response capabilities. This paper discusses Minerals Management...

The Sea Sentinels Project: Watching Waves in Brazil
This paper presents the first results of the Sea Sentinels-a project for monitoring nearshore wave conditions in Brazil by means of visual observations. The observation techniques used...

NOAA, Bioassessment Techniques and the Superfund Process
The National Oceanic and Atmospheric Administration's (NOAA) assessments of SUperfund sites require an evaluation of whether contaminants are present in an aquatic environment of concern,...

Subsidence Properties of Holocene Sediments: S. La.
As part of a comprehensive USGS-sponsored study of processes that drive subsidence and wetland loss in south Louisiana, two continuously cored deep borings (60 m and 72 m) were acquired...

Effects of Surface Brine Disposal on the Marshes in Coastal Louisiana
In 1986, more than 1 billion barrels of brine were disposed of in Coastal Louisiana. Disposal of brine into surface water body is economically practical but environmentally detrimental....

Submergence, Salt-Water Intrusion, and Managed Gulf Coast Marshes
Many coastal marshes are managed to improve wildlife habitat. Simultaneous salt-water intrusion and rapid submergence in Louisiana place additional demands on marsh managers and may become...

Coastal Non-Point Source Pollution Abatement: The Shipbuilding and Repair Industry
In cooperation with several shipbuilding and repair businesses and several state environmental regulatory agencies, site visits, waste-minimization assessments, and storm water sampling...

Coordinating Toxic Cleanup with Future Site Utilization
The Port of Olympia owns a site where former industrial activity left a legacy of toxic contamination, and which is currently involved in a cleanup action. A waterfront site which was...

Selection of Superior Planting Stocks and Development of Regeneration Techniques for Coastal Restoration: A Pilot Study
There is an increasing demand in the U.S. for wetland plants to be used for marsh restoration and coastal stability projects. However, physiologically adapted wetland plants suitable for...

Bioaccumulation in Mussels Caged in Alamitos Bay, CA
Alamitos Bay is a coastal embayment located in the southern portion of the highly urbanized Los Angeles basin. There is concern of the potential for contamination stemming from urban non-point...

Vertical Distribution of Sediment Under Waves
This paper is based on the research foundation of vertical relative distribution of sediment concentration and alluvial bed stability under waves. Amended theories of E. W. Lane and A.A....

Slides and Slumps on the Coastal Zone Between San Miguel and El Descanso, Baja California, Mexico
The coastline between Tijuana and Ensenada is being subject to intensive development, mainly as resort property, and because of the roughness of the adjacent areas inland, the coastal...

The Specific Peculiarities of Relief Transformation and Shelly Sediment Differentiation in Coastal Zone
The settling velocities values of shelly sediment considerably differ from ones of the same particles of terrigeneous material and for this reason character and intensity of hydrodynamic...

A Mathematical Model for Predicting the Motion of Polluting Surface Plumes Due to Drift Currents
The paper analyzes the problem of displacement from the offshore to the nearshore of a polluting surface plume, subject to advection generated by wind-waves and wind-currents. After a...

Aquatic Disposal of Dredged Material in the Belgian Part of the North Sea
Extensive research and study on the behaviour of dredged material after dumping in the sea has been conducted on the disposal grounds S1 S2 and Zb Oost located in the southern Bight of...
